Abstract: Field experiment was conducted at Agricultural College Farm, Raichur on vertisol during 2010-11. Experiment was laid out in split plot design with three fertilizer levels in main plot and six foliar applications of nutrients in sub plots with three replications. Effect of nutrient management practices differed significantly on growth and yield parameters of cotton. Fertilizer levels through 125 per cent of recommended dose of fertilizers (RDF) recorded significantly higher leaf area index (1.35) and seed cotton yield (17.1 q ha^-1) over other fertilizer levels. Besides, foliar application of 0.5 per cent tracel (Zn, Fe, Mn and B) recorded significantly higher leaf area index (1.36) and seed cotton yield (17.5 q ha^-1) against other treatments. In addition, interaction effect of fertilizer levels of 125 per cent RDF with foliar application of 0.5 per cent tracel recorded significantly higher leaf area index (1.40) and seed cotton yield (19.9 q ha^-1) when compared to other treatment combinations.
